Figure 23
Write to Read: Minimum DQSS, Odd Number of Data (3-bit Write),
Interrupting (CAS Latency = 2; Burst Length = 8)
DI a-b = data in for bank a, column b.
An interrupted burst is shown, 3 data elements are written.
2 subsequent elements of data in are applied in the programmed order following DI a-b.
t
WTR
is referenced from the first positive CK edge after the last desired data in pair (not the last desired data in element)
The Read command masks the last 2 data elements in the burst.
A10 is Low with the Write command (Auto Precharge is disabled).
The Read and Write commands are not necessarily to the same bank.
1 = This bit is correctly written into the memory array if DM is low.
2 = These bits are incorrectly written into the memory array if DM is low.
